A few combos I've created myself are the Luigi infinite punch and the 360 falcon. TO do the luigi infinite punch you press A the release button, then down and release. tehy're you go another combo. All you do is do A then down one after the other. As you practice you will be able to do it quick and easy, then finishing your opponent off with Up B IF THEY'RE CLOSE ENOUGH ehilr ur doing the infi punch. For the 360 Falcon you basically jump up in the air and press the opposite direction than what ur in the air then b right after it. finally turn back in your original direction to preform a 360 punch that will land you on the ground at the exact point you punch. ( Why to do this: while using the 360 punch it will almost seem like you can fly. You will basically sore a little bit less than the Final D stage although the distance is adjustable in the air..

uhhh... idk. With Kirby I normally use the dash attack, then up-b, then attempt a side-b in the air. it works(without hammer) until they get a high enough percentage. With hammer it hardly works because people can dodge
